### Changelog generation has never been so easy:
2014-11-07 10:00:01 +00:00
2015-03-18 13:26:32 +00:00
**Fully automate changelog generation** - This gem generate change log file based on **tags**, **issues** and merged **pull requests** (and split them to separate lists according labels) from :octocat: GitHub Issue Tracker.
2015-03-18 13:43:11 +00:00
Since now you don't have to fill your `CHANGELOG.md` manually: just run script, relax and take a cup of :coffee: before your next release! :tada:
2015-03-18 13:26:32 +00:00
2015-03-18 14:04:42 +00:00
>### *Whats the point of a change log?*
2015-03-18 13:26:32 +00:00
To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.
2015-03-18 14:04:42 +00:00
### *Why should I care?*
Because software tools are for people. If you dont care, why are you contributing to open source? Surely, there must be a kernel (ha!) of care somewhere in that lovely little brain of yours.

2014-11-06 13:47:56 +00:00
2015-01-21 18:14:31 +00:00
- If your **git remote** `origin` refer to your GitHub repo, then just go to your project folder and run:
2014-11-06 17:14:35 +00:00
2014-11-11 08:57:53 +00:00
github_changelog_generator
2014-11-06 17:14:35 +00:00
2014-11-24 19:20:46 +00:00
- or from anywhere:
2015-03-09 07:59:04 +00:00
- `github_changelog_generator -u github_username -p github_project`

### GitHub token
2014-11-06 17:14:35 +00:00
2015-03-18 13:36:01 +00:00
Since GitHub allow to make only 50 requests without authentication it's recommended to run this script with token (`-t, --token` option)
**You can easily [generate it here](https://github.com/settings/applications)**.
And:
2014-11-24 19:20:46 +00:00
- Run with key `-t [your-16-digit-token]`
2014-11-13 07:22:32 +00:00
- Or set environment variable `CHANGELOG_GITHUB_TOKEN` and specify there your token.
2015-01-21 18:17:57 +00:00
i.e. add to your `~/.bash_profile` or `~/.zshrc` or any other place to load ENV variables string :
export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"
2014-11-06 13:47:56 +00:00
2014-11-06 17:14:35 +00:00
So, if you got error like this:
2014-11-11 08:57:53 +00:00
>! /Library/Ruby/Gems/2.0.0/gems/github_api-0.12.2/lib/github_api/response/raise_error.rb:14:in `on_complete'
2014-11-06 14:35:53 +00:00
2014-11-11 08:57:53 +00:00
It's time to create this token or wait for 1 hour before GitHub reset the counter for your IP.

##Features and advantages of this project
2015-03-18 13:26:32 +00:00
- Generate canonical, neat change log file, followed by [basic change log guidlines](http://keepachangelog.com/) :gem:
2015-03-18 13:36:01 +00:00
- Possible to generate **Unreleased** changes (closed issues that have not released yet) :dizzy:
- **GitHub Enterprise support** via command line options! :factory:
2015-03-17 15:07:12 +00:00
- Flexible format **customisation**:
2015-03-18 13:36:01 +00:00
- **Customize** issues, that **should be added** to changelog :eight_spoked_asterisk:
- **Custom date format** supported :date:
2015-03-18 13:56:35 +00:00
- Ability to manually specify in which version issue was fixed (in case, when closed date is not match) by setting `milestone` of issue the same name as tag of required version :pushpin:
- Automatically **exclude specific issues**, not-related to change log (any issue, that has label `question` `duplicate` `invalid` `wontfix`by default) :scissors:
2015-03-18 13:52:46 +00:00
- **Distinguish** issues **according labels**. :mag_right:
- Merged pull requests (all `merged` pull-requests) :twisted_rightwards_arrows:
- Bug fixes (by label `bug` in issue) :beetle:
2015-03-18 13:43:11 +00:00
- Enhancements (by label `enhancement` in issue) :star2:
2015-03-18 13:52:46 +00:00
- Issues (closed issues `w/o any labels`) :non-potable_water:
2015-03-18 13:45:51 +00:00
- You manually can set which labels should be included/excluded. :wrench:
- Apply a lot of other customisations, to fit changelog for your personal style :tophat:
